18-Shot Straight Mortar Rack - 1.91" HDPE DR11 Tubes - FRONTLINE 18 by American Mortar Company

BALANCED POWER. ENGINEERED SPACING. PROFESSIONAL BUILD.

The FRONTLINE 18 is a mid-capacity, professional-grade mortar rack designed for builders who want significant firepower without stepping into a full-box footprint. Built in a stable 3x6 straight formation, this rack delivers clean timing, consistent lift, and rock-solid stability—making it the ideal backbone for main show sequences, straight volleys, and modular layouts.

Like all our premium units, the FRONTLINE 18 features Engineered Safety Spacing—providing critical air gaps between every tube to ensure proper thermal isolation and structural integrity during rapid mid-show sequences.

Compact enough to stay portable. Structured enough to stand alone.

🛡️ THE GOLD STANDARD: WHY HDPE DR11?

In the world of pro pyrotechnics, the material of your mortar tube is the difference between a successful show and a dangerous failure.

• Shatter-Proof Safety: Unlike PVC, which can shrapnel into sharp plastic shards during a shell failure, our High-Density Polyethylene (HDPE) is designed to swell or tear under extreme pressure, significantly reducing the risk of flying debris.
• DR11 Heavy Wall: We use the DR11 specification, providing a thick, durable sidewall that handles the high-pressure lift charges of modern 1.91" canister shells with ease. HDPE tubes are weather-resistant, built for hundreds of reloads without becoming brittle.

🔴 COMMERCIAL-GRADE CONSTRUCTION

Each FRONTLINE 18 rack includes 18 premium HDPE DR11 mortar tubes, built to professional specifications and trusted by experienced shooters.

• Inner Diameter: 1.91″ (Fits most consumer canister shells)
• Length: 12″ (Professional mortar standard)
• Bottoms: Factory-plugged and Quad-Stapled (4-point reinforcement) for maximum lift retention.
• Stability: Wide-stance, tip-resistant design built from reinforced lumber for repeat seasonal use.
